Quinnlan Varcoe is Founder and CEO of SleuthX, the AI agent for consumer digital forensics. She holds a Bachelor of Science in cybersecurity from SANS Technology Institute and designed the court-admissible forensic methodology that the SleuthX agent encodes and trains on. She is the named expert witness on litigation engagements covering family law, commercial litigation, and IP disputes.
She holds 9 active SANS GIAC certifications, including GCIH, GCIA, and GSEC. The credential mix supports qualification under Daubert and Frye.
SANS Technology Institute is the academic arm of SANS, globally the largest and most respected practitioner cybersecurity training organization. SANS curriculum is how the NSA, CIA, FBI, DoD, and allied intelligence services credential their operators. Its GIAC certifications are mandated by US DoD Directive 8140 for federal cyber roles and are treated as the industry-standard practitioner credential, being scenario-based rather than multiple-choice, and re-earned every four years rather than held for life. The same credential stack that qualifies SANS graduates for cleared federal work is what qualifies Quinn as a federal-court expert witness under Daubert and Frye.
Before founding the company, she spent roughly a decade in incident response and threat intelligence for Fortune 50 enterprises and the defense industrial base. Her LinkedIn audience of 26,000 is the primary trust-building channel for the company.
SleuthX is the productized version of that practice. Quinn owns case judgment. The AI agent scales the procedural work that previously required senior-analyst hours.
